API Authentication

You must have an account with Language I/O to access your API Key and use the API. For more information, see Creating an account in the Language I/O Self-Service Portal.

Language I/O uses header authentication. To use the API, you need a POST request to the endpoint URL, with a x-api-key header that you populate with your API key. Here is a cURL example:

curl -X GET https://agw.golinguist.com/linguistnow/resources/v1/translate -H "x-api-key: {your API key here}"

If you are an existing Language I/O customer

If you already use a Language I/O product (for example, one of Language I/O's CRM integrations) and you want to start using the API, you do not need to create a new account. Instead, submit a support request to get you API key.

Once your API key is created, you can view and refresh it in the Language I/O Self-Service Portal.
